Do price stabilisation schemes contribute to stability? Some counter-factual evidence from the Canadian barley market
研究了价格稳定计划对生产者预期的影响，通过加拿大草原大麦市场的理论模型，比较了不同稳定方案与无稳定情况下的价格收敛和方差，发现方案选择会影响市场价格生成过程。
The impact of price stabilisation schemes on producer expectations has generally been ignored by policy makers. Using a theoretical model of the Canadian prairie barley market, unconditional mean price and two-year moving-average price stabilisation schemes are compared with no stabilisation, assuming rational expectations. Both price convergence and variance were affected by the choice of the price stabilisation scheme. This illustrates the influence price stabilisation schemes can have on the stochastic process generating market prices
